The five stories PR pros need to know on Tuesday morning, 7.14.2015

1. A group of world powers has reached a deal with Iran that restricts its ability to create nuclear weapons in exchange for rolling back sanctions. President Obama addressed the nation on the accord at 7 am, saying, "This deal is not built on trust. It is built on verification." Not everyone is a fan. Israel’s prime minister called the agreement a "historic mistake" on Tuesday morning. Oil prices dropped on the news.

2. Reddit chief engineer Bethanye Blount has stepped down after less than two months on the job and only a few days after CEO Ellen Pao left the company’s top position. Blount told Re/code that she had lost confidence in Reddit’s direction.

3. Hillary Clinton’s comments on the "sharing economy" and matters of income inequality raised by it have raised eyebrows in Silicon Valley. Menlo Ventures partner Shawn Carolan said, "Governmental leaders should be happy and look for more partners to encourage that type of innovation," according to Business Insider. Other tech-sector heavyweights echoed Clinton’s comments.

4. Wisconsin Governor Scott Walker kicked off his 2016 campaign on Monday afternoon, appealing to blue-collar voters in the suburbs outside Milwaukee. His family sat down with ABC News on Monday, joking about his around-the-house habits like wearing jean shorts.

5. New York City has reached a $5.9 million deal with the family of Eric Garner, the man who died nearly a year ago after he was arrested by New York Police Department officers on Staten Island in an incident caught on video. The family had sought $75 million in damages.
